Post game gang control

Hey, im using the GOTR for quite a while now and love it!
Finished the game with it, and i love that i have still a few areas where i can go to fight other gangs thanks to the "Post game gang control" option!

However, is there a way, with a mod or save game editor ( i had one in SR3 ) where i can edit which hood I own or the gangs own? I would love to give ALL hoods back to the gangs so i can fight the gangs everywhere again! like in the beginning of the game.

Also i don't like how the Saints Hoods are too crowded with saints, which sounds stupid, but its like every second civilian is a saint now. Leave some of the killings to me! which is another reason why i want to give the gangs their hood back
